I think the majority of SE piston crashes are due to fuel mismanagement.

Actually, the overwhelming majority of them are pilot error, but this one does indeed appear to be logistics related. After flying for a fairly long time and maneuvering without difficulty, the 210 appears to have lost engine power. Most probable cause for that IS fuel mismanagement exhaustion.

The majority of all accidents is due to pilot error. Like 94% or so.
Statistically the majority of SE piston accidents are caused by duke mismanagement. That’s running outta gas. Closely followed by crashing with an empty tank and a another one that still contains fuel.
